Electric quadrupole moment of the state in : A relativistic coupled-cluster analysis
K. V. P. Latha, C. Sur, R. K. chaudhuri +2
The electric quadrupole moment for the state of , has been calculated using the relativistic coupled-cluster method. Earlier a similar calcul…
Branching ratios of radiative transitions in O VI
Chiranjib Sur, Rajat K Chaudhuri
We study the branching ratios of the allowed and forbidden radiative transitions among the first few (9) fine structure levels of O VI using relativistic coupled cluster theory. We…
Effects of partial triple excitations in atomic coupled cluster calculations
Chiranjib Sur, Rajat K Chaudhuri
In this article we study the effects of higher body excitations in the relativistic CC calculations for atoms and ions with one valence electron using Fock-space CCSD, CCSD(T) and…
Relativistic multi-reference Fock-space coupled-cluster calculation of the forbidden $6s^2^1 S_0 \longrightarrow 6s5d^3 D_1$ magnetic-dipole transition in ytterbium
Chiranjib Sur, Rajat K Chaudhuri
We report the forbidden $6s^{2} ^{1}S_{0}\longrightarrow6s5d ^{3}D_{1}$ magnetic-dipole transition amplitude computed using multi-reference Fock-space coupled-cluster theory. Our c…
A relativistic unitary coupled-cluster study of electric quadrupole moment and magnetic dipole hyperfine constants of ^{199}Hg^{+}
Chiranjib Sur, Rajat K Chaudhuri
Searching for an accurate optical clock which can serve as a better time standard than the present day atomic clock is highly demanding from several areas of science and technology…
